I have a website which gets around 15 K views a day, that is in a specific niche. I have worked hard to build up my reputation and intend to keep it this way. On my website I offer legit software to my users. I am planing to WL software that is similar to the one that I am selling now with a margin of profit which will be about twice as big. I want to build a website for this software where I can freely advertise on Facebook and google. I was wondering is it possible to use the Facebook pixel which is on my popular website to re-target my users and push Facebook ads to my white label product website.
Yup - go for it! Obviously won't be 'free' (not sure if you meant your 'freely' comment as in freedom or free).
Yes retargeting is powerful, you should give it a shot!
I just wasn't sure if Facebook would let me use a pixel from website to do re-targeting advertisement for another website (white label one).
